BIOL 1201 Chapter 16 (Final Exam)
Crousillac CORRECT 100%
Who introduced the double-helical model for the structure of DNA? -
ANSWERJames Watson & Francis Crick
Hereditary information is encoded in ________ and reproduced in all cells of the
body - ANSWERDNA
Directs the development of biochemical, anatomical, physiological, and (to some
extent) behavioral traits - ANSWERDNA Program
Evidence for DNA as the genetical material came from studies of viruses that infect
bacteria - ANSWERBacteriophages
To determine the source of genetic material in a bacteriophage (T2), they designed
an experiment showing that only one of the two components of T2 (DNA or protein)
enters an E. coli during cell infection - ANSWERHershey and Chase Experiments
What are the two components of T2 (a bacteriophage)? - ANSWERDNA & Proteins
Reported that DNA composition varies from one species to the next -
ANSWERErwin Chargaff
State that in any species, there is an equal number of A and T bases, and an equal
number of G and C bases - ANSWERChargaff's Rules
What are the four bases in DNA? - ANSWERA-T-G-C
In DNA, A (Adenine) =? - ANSWERT (Thymine)
In DNA, G (Guanine) =? - ANSWERC (Cytosine)
DNA base that is known as the DNA nucleotide - ANSWERG (Guanine)
Used X-Ray crystallography to study molecular structure - ANSWERMaurice Wilkins
& Rosalind Franklin
Rosalind Franklin produced a picture of the DNA molecule using crystallography,
which showed that DNA was _______ - ANSWERHelical
Where the two DNA strands are separated, opening up a replication "bubble" -
ANSWEROrigins of Replication
What direction does DNA replication proceed in? - ANSWERBoth
